A printing machine includes a printing table for printing groups of objects presented in an entry support and an exit support, a transfer system disposed between the printing table and a loading system, on the one hand, and an offloading system, on the other hand. The transfer system transfers the objects one by one. The loading and offloading systems include holding arrangements which take up simultaneously and move a group of objects between the entry support or the exit support and the intermediate supports. The intermediate supports support the group of objects disposed with a predetermined spacing. Spacing modification arrangements modify the spacing of the group of objects from an entry spacing to the predetermined spacing or from the predetermined spacing to an exit spacing. The transfer system transfers the objects between the printing table and the intermediate supports.
